Elizabeth Montgomery plays a rare pre-Bewitched role as a floozy jazz groupie who's the ex-wife of one of Staccato's former band mates. Out of the blue she shows up at Waldo's the jazz club (and Staccato's ""office"") to enlist Staccato's help, telling him she's almost just been robbed of expensive jewelry she was taking from work. What she was doing with the jewels and why she was taking them from the store she works at piques Staccato's interest (as does the fast-talking and shapely Ms. Montgomery). He's immediately suspicious, but cautiously takes on the case. While he's escorting her home (supposedly with the jewels) they're accosted by a mugger who knocks Staccato out, grabs the jewels, and takes off. The next morning, nursing the bump on his head, Staccato gets a visit from an insurance adjuster who reads him the riot act. Unfazed, Johnny tells the adjuster to take a hike, goes into the bathroom and viola! pulls the jewels out from the soap dispenser. Who set him up? Could it have (thetvdb.com)
